The machin/cutting ability AND PROCESS efficiency evaluation of Abrasive Waterjet

conference paper

English

Annotation: Special model is based at a shock waves theory. The model requires cutting process presence of arbitrary material and it is situated in cutting kerf. Dynamical removal phenomena initiates shock wave and an echo is consequence at jet interface, at erosion front mainly. The arrangement of the experiments was aimed to catch a phenomena dynamics by means of high-speed camera. Specific setting of Abrasive Waterjet (AWJ) process parameters of the cutting flow at the interface - final workpiece margin /free space - faces to a nose creation. The nose is bounded as a triangle and it is a consequence of overshooting phenomenon. An special test specimen is designed for cutting/machining ability of AWJ processes. It provides job-shop tests according the requirements to quick and cheap, but enough exact and repeatable, operative proofs. The test is founded at nose measurement and obtained dependences serves to fast and exact evaluation of cutting process efficiency. It will be source of new economic savings and contribution of cutting technology of the AWJ.
